No. People who wish to enter the asylum process are dealt with as such. I can't imagine too many holidaymakers or actual economic migrants from stable countries will want to be filtered into the asylum route.
It seems a better solution than feeding a trafficking black market and risking further channel deaths, frankly. Which is what you're suggesting
I notice that all your responses talk about asylum seekers. Well, there's little doubt that many on these channel runs are economic migrants, is there.
When the Beeb interviews them and they all have Apple phones, many of them outright say they want to come for "a better life", which is entirely different to "escaping persecution" or "fleeing for my life". Quite often they interview Iraqis, and I'm not sure Iraq is currently that bad that you'd be fleeing in fear of your life.
They may simply believe that the UK is the place to go for better prospects. Whilst not a bad motivation, per se, it's not enough to warrant literally unlimited migration as you are suggesting. We don't hate foreigners, but you can't just relocate all the world's poor to the UK.
We would be opening ourselves not just to asylum seekers, but to people who are simply fed up of living in a less well developed country.
Whilst I have incredible sympathy for people living in **** holes, where corruption is rampant, and opportunities limited, the answer cannot be to funnel them all here, if their lives aren't actually in danger.
Now you might say, "Who would attempt that crossing if they weren't in danger?"
Well, they aren't in danger in France, for a start. But secondly, there are a lot of young men in those groups, and there will be the usual arrogance and bravado of young men. And after all, whilst not exactly safe, most of the boats do either make it across successfully or get intercepted and brought the rest of the way in safety.
Ultimately, I don't see how the UK can take unlimited migrants, of the economic kind. And I don't see how you'd stop the economic migrants. Once in the country it's too easy to just disappear.
So then what? We'd have vast groups of people sleeping rough or herded in camps living in squalor in the UK, rather than living in camps in France.
I think with what you're proposing we'd be overwhelmed quite quickly, tbh. Where would we put all the tens of thousands of people who would make a bee-line for the UK?
